Upgrading from v6 to v7?
Please review the Upgrading Decisions (v6 to v7) article for IMPORTANT CONSIDERATIONS.

The following demonstrates how to install v7 on Amazon Web Services. Doing so provides server admins the flexibility and scalability of AWS within a Decisions-based environment.


Decisions is a robust software with a wide variety of use cases. The deploying organizations' Senior Database Administrator (DBA) should be involved in recommending resources.

  • Standard Specifications - recommended for optimal performance in the average standalone server environment
    • local development installs may run on reduced system requirements
  • Enterprise Specifications - recommended for data-heavy clustered environments and/or organizations with long procurement/change request cycles

AWS Specifications

The specifications outlined in this article are intended for the Application Server based on these server types:

  • Production Server: a live environment where created processes are leveraged by end-users (customers) 
  • Non-Production Server: non-customer facing environment used for testing and development to assess production readiness
  • Repository Server: non-customer facing environment used to help maintain version control and migrating projects between servers

To allow Decisions Server to connect an RDS instance, the RDS Security Groups and/or VPC must be configured to allow communication from the EC2 Instance.

Start an EC2 Instance

Launch a new Windows Server instance and choose the size/OS version in accordance with recommended hardware/software specs. 

Install on EC2 Instance

  1. Remote desktop into the instance and run DecisionsServerInstaller.exe
  2. Follow the installation guide until reaching the Database Setup screen.
  3. From the RDS Dashboard, find and copy the endpoint address, via Endpoint, for the RDSInstance.
  4. In the Decisions Installer, under Database Type, select MS SQL. Then, enter the endpoint address in DB Server.
  5. Back in the RDS Dashboard, find and select the RDS Security Group

  6. Under Security Group > Inbound, click Edit

    From the Edit inbound rules window, click Add Rule and define a Rule that allows MS SQL from the Internal IP Address of the EC2 Instance. Then, click Save.

  7. Back in the Database Setup screen of the installer, select Test to ensure that there is successful communication between the two servers.

    Continue and finish installation
